Research examining driver distraction often makes use of driving simulators, as they allow for a number of driving performance measures to be examined in a relatively realistic and safe driving environment. (...) First, simulators provide a safe environment to conduct research that is too dangerous to be conducted on the road. (...) Second, greater experimental control can also be applied in driving simulators compared to onroad studies, as they allow the type and difficulty of driving tasks to be precisely specified and potentially confounding variables such as weather can be eliminated. (...) Third, the cost of modifying the cockpit of a simulator to address different research questions may be significantly less than modifying an actual vehicle and ensuring that the modifications are roadworthy or meet the design rules. (...) Fourth, a large number of driving performance measures can be examined in driving simulators, such as speed control and maintenance and lateral position on the road. (...) Finally, a large number of different test conditions (e.g., night and day, different weather conditions or road environments) can also be administered with relative ease (...).

When drivers perform a secondary task while driving, they usually complete this task through a series of brief glances (1 to 2 seconds) at the object interspersed with glances at the roadway. Eye glance studies record and measure the frequency and duration of glances towards the secondary task which gives a measure of the total “eyes off road time”, and hence the visual demand or interference associated with performing the task (...). Total eyes-off-road-time is a widely accepted and valid measure of the visual demand associated with the performance of a secondary task and is highly correlated with the number of lane excursions committed during secondary task performance (...).
